Answer:
B. 3x² +2 = 0
Step-by-step explanation:
The equation of A has a couple of real roots. We're pretty sure there are complex numbers that will satisfy this equation, but we don't know how to find them. (We suspect a typo, and that the equation is supposed to be 2x² +1 = 7x, which has only real roots.)
__
The equation of B can be rewritten as ...
x² = -2/3
This will have complex roots.
__
The discriminants of both equations C and D are positive, so those have only real roots.
2x² -5x -1 ⇒ d = (-5)² -4(2)(-1) = 33
3x² -6x -1 ⇒ d = (-6)² -4(3)(-1) = 48
Answer:
7.92, 7.94, 7.999, 8.061, 8.1, 8.087
Step-by-step explanation:
There isn't exactly a step by step explanation.
7.92 is smallest because while all the ones with 7 in it have a 9 in the first digit, the second digit is the smallest out of those. you can work your way up from there
Sorry I don't know but good luck!
